6 weeks later, I am suffering from occasional severe fatigue still - these days, it manifests itself after 8-9 hours or so and results in a crash where I have to sleep for 40mins+. If I don’t struggle through and go to bed then, it will screw up my sleep schedule. During the 2 weeks of COVID, it was way worse and I could sleep 3/4s of an entire day and still be tired.
This is getting better - I push myself everyday just a little more and now can exercise for 2 hours straight and carry on, but it’s night and day different to pre-COVID behavior and I imagine it will be through to Christmas before I am back to “normal” (touch wood).
